Parental care refers to the behaviors exhibited by parents toward their offspring that increase the offspring's chances of survival. These behaviors can include nest building, feeding, protection from predators, and teaching essential skills. The level and type of parental care vary widely across the animal kingdom, from minimal investment in some invertebrates to extensive, long-term care in mammals and birds. Understanding parental care strategies helps us appreciate the diversity of life and the evolutionary pressures that shape animal behavior.
